Pirastro "New Formula" Tonica Synthetic Core Violin Strings

First of all during the last 15 years Pirastro has developed new concepts and ways of constructing strings, made important experiences in string technology and gained new expertise. During that development phase Pirastro cames out with such popular strings as the Obligato, Evah Pirazzi and Passione. Today Pirastro has a different knowledge and new techniques at hand to design a Nylon core string set. As a result they have newly constructed all of the Tonica strings except for the E steel wound with aluminum string. The changes result in an overall improved string set. 

  • The response is easier and faster.
  • Playing pianissimo has considerately improved.
  • All bow strokes are possible resulting in smooth crossings from one note to another.
  • Easier right hand articulation and tone attack.

Sound Characteristic

  • The Tonica has now a livelier and more round sound, which is open and direct with less side noises.
  • The projection and brilliance have been upgraded. This excess of brilliance, however, does not mean that the Tonica has lost its warmth.
  • The set harmony is now much better.

The set harmony is now much better by exchanging the steel/aluminum E with the Silvery Steel E 25.5. The D string of the former Tonica set is wound with aluminum, which results in a very warm and soft sound, however at the expense of the set harmony and a certain lack of brilliance. Since the second half of the 1990's it is common for Pirastro standard string sets to have a silver wound D string included. This allows a perfect set harmony with a brilliant sound that has good projection. This is the reason why the standard set article numbers 411021 & 411025 now have the Silvery Steel E and the silver D included
